. Be it known that I, LAWRENCE KEARNEY WA'rRoUs, a citizen of the United States, and a-resident of Sea Cliff, in the county of Nassau and State of New York, have invented a new and Improved Nut-Lock, of which the following is' a full, clear, and exact description.

My invention relates to nut locks, my special purpose beingto provide a construction wherein a nut is mounted upon a sleeve, and the sleeve in turn is mounted upon a bolt,

Aand so arranged that in consequence of pressurey lof the nut upon the sleeve none of the parts can readily move relatively to other parts.

- Reference is to be had to the accompanying drawings formino a part of this specification, in which. simi ar characters of refer-v ence indicate corresponding parts in all the figures. l A

-F igli're'l is a view partly in section and partly in elevation, showing. my improved nut lock, the parts in this instance appearing 5 as theydo before the nut is tightened; Fig. 2 is a view similar to Fig. 1, but differs therefrom in showing the nut and sleeve as tightened; and Fi 3 is a section on the line 3-3 of Fig. 2, loo ing in the vdirection of the arrow, and showing means for preventing the vsleeve from turning relatively towthe bolt.

A bolt 3 is provided with a head 4 inteal with it' and is further provided with a t read 5.

v At 6 is shown the work to which the bolt is to be applied-say two plates to be clamped together.

l A.t 7 vis a washer encircling the bolt and engaged by the head thereof.

A sleeve 8 is provided inwardly adjacent to one ofits' ends with a thread 9 and is further provided with a smooth inner surface 10 which extends from thev thread 9 to the oppositeend of the sleeve. The sleeve 8 is provided internally with ribs 11 each having a sharp inner'edge' so as to out across the threads 5 of the bolt. At 12 are slots in the sleeve 8, these slots extending from the inner thread 9 to the opposite end of the sleeve. The sleeve'S is further provided with an annular Han' e f3 which fserves the purpose of' a shoe.

his' flange is provided with notches 14.,

At 15 is a revoluble nutwhichis threaded internally and free to turn upon the sleeve S. This nut is provided with lugs-.flwhich are adapted to fit into thefnotcheslll.

l`he operation of my device is-*as follows: The bolt being thrust through the plates `6 so that the head 4 comes intoengagenient with the washer 7, the sleeve 8',is slipped over the opposite end vof the bolt, so that the inner thread 9 engages the thread. The nut 15 is next brought into engagement with the sleeve 8 and is turned. 'lhe rotation of the nut causes the sleeve 8 to 'turn until the flange 13 is brought against the adjacent plate 6. The rotation of the sleeve 8, sulicient to bring the tiange-l into enr.

gagement with the plate 6, 1s a comparatively easy matter owing to the fact that, as shown 1n Fig. 1, the two divergent portion's of the sleeve 8 upon opposite sides of' and prevents, or at least greatly limits,

the rotation ofthe sleeve 8. The nut 15 being turned still further, the slot 12 is contracted as indicated in Fig. 2, so that the nut passes to the left according to the g rotation of the sleeve 8 is thus effectively prevented. The ribs 11 slightly out the threads 5, but the mutilation is trivial and does not materially deface the bolt. When the nut' 15 is broufrhtinto engagement with the flan e 13, a little` further rotation of the nut. rings one of 'the lugs 16 into some one of the notches 14. The flange has now no power to yield, exce t to spring .slightly inward-that is, towar the axis of,the bolt 3 as a center, and when the lug 16 lodges in one of the-notches 14 the sleeve 8 is perfectly rigid in relation to the bolt and the :nut 15 equally rigid relatively to the sleeve.

With the parts thus fixed 1n position', neither uros, until it lodges against the flange 13. 'In doing this, the ribs ll are forced across and into the threads 5 so that backward sey gaging the same, said sleeve having a split- 2.
